RollingFileAppender: log files with constant extension and composite name

[Mike Blake-Knox]

I'd like current messages to always be logged into a file with the same name (e.g., mylogs.log).  When a file hits a maximum size I'd like to have the file renamed and have future logs go into a new file with the same name as before (i.e., mylogs.log). The old file would be renamed to a name that includes a sequence number and date (e.g., mylogs20051109.2.log for today's second log file). It would be OK if the date didn't get added to the name until the next day.

The RollingFileAppender does this fine except that the sequence number becomes the file extension.

Is there a way to configure the RollingFileAppender to do this?

I'm currently using the following configuration:

    <appender name="Dev4RollingFile" type="log4net.Appender.RollingFileAppender">
      <file value="C:\\ProphIT_CTI" />
      <maximumFileSize value="500KB" />
      <maxSizeRollBackups value="5" />
      <datePattern value="yyyy-MM-dd'.log'" />
      <staticLogFileName value="false" />
      <rollingStyle value="Composite" />
     <appendToFile value="true" />
      <countDirection value="0" />
      <layout type="log4net.Layout.XmlLayoutSchemaLog4j" />
    </appender>

Thanks.
